Completely agree, this deal is not enough....if this deal goes south for Cubist watch their stock tank. Cubist needs to offer some stock to the $13.50 to sweeten the pot or raise the cash price. I have a feeling a White Knight is riding to the rescue.
I bought some additional calls on this dip under 13.6, just in case another bid emerges, downside is low. Wow ECYT is trading like it's going to be acquired. Sold some puts on the last big dip to $12, should have bought stock, but I have lots of IMGN.
